Example 1

A cable protection tube convenient for sealing is provided, in order to connect adjacent tubes and seal the two most ends of the tubes, the inventor is provided with a sealing ring 2, a sealing gasket 3 and a limiting sleeve ring 4, as a preferred embodiment, as shown in fig. 1, 2, 3 and 4, the cable protection tube comprises a tube body 1 and a tube cap 10 arranged at the top end of the tube body 1, a sealing ring 2 is sleeved at the rear end of the tube body 1, the front end of the tube cap 10 is clamped with the sealing gasket 3 and the limiting sleeve ring 4, an annular groove 11 is arranged at the inner side of the front end of the tube cap 10, a plurality of upper convex strip groups 20 are arranged at the upper half part of the outer side of the sealing ring 2, a plurality of lower convex strip groups 21 are arranged at the lower half part of the outer side of the sealing ring 2, a plurality of upper convex strip groups 20 and a plurality of lower convex strip groups 21 are distributed in a staggered manner, a convex ring 30 is arranged at the outer side of the sealing, the outer side surface of the horn end 41 is provided with external threads 42, and the outer side surface of the horn end 41 is provided with a plurality of annular contraction joints 43 at equal intervals.

In this embodiment, sealing washer 2 and sealed pad 3 all adopt the rubber material to make integrated into one piece structure, and its pliability is good and the leakproofness is good, makes sealed effectual and durable, and spacing lantern ring 4 adopts the PP material to make integrated into one piece structure, and its matter is light, toughness is good and intensity is stiff, makes its durable.

Further, the pipe cap 10 of one pipe body 1 is in sleeve joint fit with the sealing ring 2 at the rear end of the other pipe body 1, and the adjacent pipe bodies 1 are tightly matched and sealed through the sealing ring 2. When the sealing ring 2 is extruded into the pipe cap 10 and is deformed under pressure, the plurality of upper convex strip groups 20 and the plurality of lower convex strip groups 21 are distributed in a staggered manner, so that the sealing ring 2 is tightly matched and sealed with the inner side of the pipe cap 10.

Specifically, the front end face of the sealing gasket 3 is provided with a plurality of through holes 31 for passing through a plurality of cables, so that no gap exists between the cables, and the sealing effect is achieved. The inner diameter of the boss 40 is larger than the maximum diameter of the through holes 31, and the boss 40 plays a limiting role on the sealing gasket 3 and prevents the sealing gasket from slipping from the pipe cap 10.

Example 2

As a second embodiment of the present invention, in order to make the stop collar sleeve more tightly, the inventor has set the pre-tightening ring 5, as a preferred embodiment, as shown in fig. 5, the outer side of the stop collar 4 is connected with the pre-tightening ring 5, the inner side of the pre-tightening ring 5 is provided with the internal thread 50, and the internal thread 50 is in threaded connection with the external thread 42.

In this embodiment, the pre-tightening ring 5 is made of PP material and has a light weight, good toughness and rigid strength, so that it is durable.

Further, the internal diameter of pretension ring 5 equals with the external diameter of stop collar 4, avoids pretension ring 5 to rock in the stop collar 4 outside, can extrude the loudspeaker end 41 deformation and closely laminating the pipe cap 10 outside simultaneously, makes stop collar 4 and pipe cap 10 cooperation firm.

Specifically, the rear end external diameter of loudspeaker end 41 is greater than the external diameter of stop collar 4, the medial surface of loudspeaker end 41 flushes with the medial surface of stop collar 4, this structure does benefit to pretension ring 5 and screws outside stop collar 4 and make stop collar 4 sticis pipe cap 10, promptly after screwing in pretension ring 5 outside stop collar 4, along with pretension ring 5 in the continuous precession of loudspeaker end 41, because the internal diameter of pretension ring 5 is unchangeable, and the external diameter of loudspeaker end 41 is progressively bigger and bigger backward, thereby deformation under the extrusion of pretension ring 5, the contraction joint 43 provides the dodge space for deformation promptly, the external diameter of loudspeaker end 41 is the same with pretension ring 5 internal diameter, must its inside edge extrude pipe cap 10 lateral surface, thereby stop collar 4 tightly sticks firmly outside pipe cap 10 under the cooperation of pretension ring 5.

In addition, the outer side surface of the pre-tightening ring 5 is provided with a plurality of lugs 51 at equal intervals, so that the pre-tightening ring 5 can be screwed by stepping on the lugs 51.

When the cable protection tube convenient for sealing is used, the sealing ring 2 is sleeved at the rear end of the tube body 1, when the head and the tail ends of the adjacent tube bodies 1 are spliced, the sealing ring 2 is clamped between the tube cap 10 and the rear end of the tube body 1 to play a sealing connection effect, a plurality of cables pass through the connected tube bodies 1, finally, the tube bodies 1 at the head and the tail ends of the tube bodies 1 are clamped with the sealing gaskets 3, only the rear end of one tube body 1 is exposed, the size of the clamped sealing gasket 3 is matched with the inner diameter, the cables pass through the through holes 31 one by one, the limiting ring 4 is sleeved outside the tube cap 10, the pre-tightening ring 5 is taken out and sleeved outside the limiting ring 4 and screwed into the horn end 41, along with the continuous screwing-in of the pre-tightening ring 5, the horn end 41 deforms under the extrusion of the pre-tightening ring 5 and is extruded to extrude towards the outer side surface of the tube cap 10, so that the limiting ring 4 is tightly attached outside the tube cap 10 under, both guaranteed that pipe cap 10 department is sealed, also made sealed firm lastingly, also be connected with the structure with spacing lantern ring 4 and the same size difference of pretension ring 5 structure in the same way another body 1 rear end, make its rear end also sealed to the cable is airtight space in a plurality of bodys 1, has avoided the entering of moisture and foreign matter.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
